A: The answer for what is a scale in music can be give as :

A scale is defined as a series of notes that are played one after another – usually 7, to
make up a specific sound, or serve as the starting point for any piece of music or
composition.

There are two main types of scale 1) Major Scales 2) Minor Scales. There is one more type of scale, that is known as Chromatic Scale.

The major scale

Let's see what is a major scale in music : A major scale, an auditory sensation with that you simply are definitely familiar, is made of 7 whole (W) and half (H) steps in subsequent sequence: W-W-H-W-W-W-H. The very first pitch from the scale is also known as the tonic, is the pitch where the remainder of the scale depends. Whenever the scale ascends, the tonic is replicated right at the end an octave higher.

The minor scale

The other scale with that you are probably quite familiar is a minor scale. There are lots of scales that one may possibly express as minor, all of which have a characteristic 3rd scale degree that's lower than the one had in the major scale. The minor scale most commonly applied to tonal music from the Common Practice period depends on the aeolian mode , which might possibly be known as the natural minor scale.The natural minor scale is comprised of 7 whole (W) and half (H) steps in the following order: W-H-W-W-H-W-W.

The Chromatic Scale

The chromatic scale is made up wholly of 1/2 steps, & uses each and every pitch on the piano within just one octave.
